Ignoring A Level In A Multilevel Model: Evidence From Uk Census Data, Mark Tramner, David Steel

Professor David Steel

Because of the inherent multilevel nature of census data, it is often appropriate to use multilevel models to investigate relationships between census variables. For a local population, the data available from the census allow a three-level nested model to be assumed, with an individual level (level 1), an enumeration district (ED) level (level 2), and a ward level (level 3). The consequences of ignoring one of the three levels in this model are assessed here theoretically. Empirical results, based on 1991 UK Census data, are also provided, comparing the variance components estimated from the three-level model with analyses based on …

Technology Corner Visualising Forensic Data: Evidence (Part 1), Damian Schofield, Ken Fowle

Journal of Digital Forensics, Security and Law

Visualisation is becoming increasingly important for understanding information, such as investigative data (for example: computing, medical and crime scene evidence) and analysis (for example: network capability assessment, data file reconstruction and planning scenarios). Investigative data visualisation is used to reconstruct a scene or item and is used to assist the viewer (who may well be a member of the general public with little or no understanding of the subject matter) to understand what is being presented. Analysis visualisations, on the other hand, are usually developed to review data, information and assess competing scenario hypotheses for those who usually have an …

Difference Between Far-Infrared Photoconductivity Spectroscopy And Absorption Spectroscopy: Theoretical Evidence Of The Electron Reservoir Mechanism, Tadashi Toyoda, Maho Fujita, Tomohisa Uchida, Nobuyoshi Hiraiwa, Taturo Fukuda, Hideki Koizumi, Chao Zhang

Faculty of Engineering and Information Sciences - Papers: Part A

The intriguing difference between far-infrared photoconductivity spectroscopy and absorption spectroscopy in the measurement of the magnetoplasmon frequency in GaAs quantum wells reported by Holland et al. [Phys. Rev. Lett. 93, 186804 (2004)] remains unexplained to date. This Letter provides a consistent mechanism to solve this puzzle. The mechanism is based on the electron reservoir model for the integer quantum Hall effect in graphene [Phys. Lett. A 376, 616 (2012)]. We predict sharp kinks to appear in the magnetic induction dependence of the magnetoplasmon frequency at very low temperatures such as 14 mK in the same GaAs quantum well sample used …

Evidence-Free Policy: The Case Of The National Injury Insurance Scheme, Mark Harrison

Faculty of Engineering and Information Sciences - Papers: Part A

The Productivity Commission report 'Disability Care and Support' recommends tort liability be replaced by a compulsory, government-run, no-fault scheme. But theory and evidence indicate moving to a no-fault scheme will increase the accident rate. Even a move from non-risk-rated third-party insurance to non-risk-rated first-party insurance reduces incentives for care. A no-fault scheme is not superior to current policies; genuine reform will need to be informed by law and economics literature.

Characterising Poly (Vinyl Chloride)/Aliquat 336 Polymer Inclusion Membranes: Evidence Of Phase Separation And Its Role In Metal Extraction, Nurul-Syazana Abdul-Halim, Philip G. Whitten, Long D. Nghiem

Faculty of Engineering and Information Sciences - Papers: Part A

The miscibility of the base polymer poly (vinyl chloride) (PVC) and the extractant Aliquat 336 in polymer inclusion membranes (PIMs) was investigated by characterisation of thermal transitions using differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The extractions of Cd (II) and Zn (II) using PVC/Aliquat 336 PIMs with different base polymer/extractant composition and different extraction temperature were also investigated. Changes in the PIM's heat capacity measured by DSC were small, thus, could only be used to determine the glass transition temperature (Tg) of PIMs with low Aliquat 336 content. On the other hand, DMA results clearly identify the …
